Hi all,
I find that `M-x shell' would end in some endless loop when
`file-coding-system-alist' has been set to something like
,----
| (setq file-coding-system-alist
| '(("\\.dz\\'" no-conversion . no-conversion)
| ("\\.g?z\\(~\\|\\.~[0-9]+~\\)?\\'" no-conversion . no-conversion)
| ;; [...]
| ("" utf-8 . utf-8)))
`----
namely, set the default coding system for file I/O operation to
utf-8.
If i replace it with some other values, like undecided(the default
value), gb2312, etc. It has no such problem.
Emacs is built from cvs 20070515.

I can't reproduced that problem. Could you please use M-x
report-emacs-bug RET to report the bug? That command
inserts many useful information in *mail* buffer. It may be
ok to change the To: address to emacs-devel@gnu.org by hand.

I'd rather post via newsgroup. Or i'll have to subscribe to
report-emacs-bug first?
Below is the buffer info when invoking report-emacs-bug. Emacs is
started by `emacs -Q'.

I tried with that same locale, but still couldn't reproduce
the problem. It may be a powerpc-specific problem. Can
someone else using Emacs on that platform reproduced it?
By the way, you wrote:

Please do M-x toggle-debug-on-quit RET, and the M-x shell.
Does Emacs react on C-g when it seems to be in endless loop?
If so, what is shown in *Backtrace* buffer?

Yes.

Nothing ! It doesn't even create a *Backtrace* buffer. Just display
"Quit" in the minibuffer. But *shell* buffer itself gets created
successfully at the same time.

Setting debug-on-quit to non-nil might help you produce a backtrace.

Ummmm. Then please run Emacs under gdb and type C-z in gdb
session when Emacs is in endless loop. Then,
(gdb) bt
will tell you where you are.
The detail is in the file etc/DEBUG (please search for
"infinite loop").

I'm sorry. After a rebooting, i'm unable to reproduce it myself. I'll
report again if i catch this problem again.
